Application led October 23, 1920. Serial No. 418,998.

To all whom t may concern:

Be it known that WILLIAM M. JANPOLE, a citizen of the United States,residing at New York, in the county of Manhattan and.

the primary object ofthe invention is to provide a new and improvedYlath in combination with other elements to provide new featuresheretofore unknown and unused in the art of construction materiaL It -isan express purpose of my invention to provide an improved method, theresult vof which will be an article of manufacture particularly7applicable for use in building structures as a covering for walls,ceilings and the like and for other practical purposes and uses.

It is a further object of the invention to provide a most essentialfeature in structural material which is superior to any product of thischaracter heretofore utilized f o'r the same purpose and' which willovercome the many diiiculties experienced in the use of elements forwhich my improved article' is-a substitute.' I

Furthermore and more particularly it is an object .of my inventiontoprovide an improved wall covering=in which laths, slats, strips or thelike with my new features are anchored to the backing and particularlyaffording a means whereby plaster, cement, stucco, 0r other similarmaterials are most effectively secured to the covering.

It isa still further object of my invention 'combining the novelfeatures of the lath, slats, strips or the like with other elementsconstituting -a wall covering, to provide a sanitary, damp, vermin,sound proof, impervious to water, air-tight, heat and cold insulatingand lire-resisting Wall covering. The structural element so organizedand produced is inexpensive and economic in manufacture as well aseconomic in its utilization, is of long life and great durability,convenient inhandling and most practical in itsapplication, in that itforms a firm and rigid construction.

In carrying out the objects of m invention, I employ a body Iof paper orot er suit-v able material to which is applied on one surface a coating,in plastic form, of asp-haltum, or some similar substance or otheradhesive flexible suitable materials in a heated stage, to which latterin turn are applied a plurality of improved laths, slats, strips or thelike, being disposed parallel and at a desired distance apart, themethod of application being such as to cause a positive'ad, hesionl intothe plastic coated form of asphaltum of any other suitable materialutit5 lized, and the application of pressure to the above 4mentionedlaths, slats, `Strips or the like for the purpose of firmly pressing thesame into the asphaltum or other material.

While I have stated that the paper is coated with a material orsubstance in a heated stage, I do not desire to limit myself to such, asthere m-ay be instances wherein a coating of material non-heated, yetflexible and adhesivein" character, may be utilized for this same purse. v

In thus havingt `eelements united as heretofore specified, a structuralelement is constituted which may be worked up into suit-4 -able shapesand' forms for subsequent use 80 and serves as elements of building wallc011- struction, ceilings or the like or for any other purposes desired.

In the accompanying drawing, forming a part of the referred tospecification and claims, and embodying my invention, combining innovelty an improved lath, slat, strip or the like, in combination withother elements, I have illustrated in- Figure 1, a fragmentarytransverse section 9o through a structural element embodying thepreferred form of my invention;

ln describing the invention I shall refer to the drawing wherein similarreference characters designate corresponding parts throughoutthe'several views and in which` 1 designates a body of a backingconstructed of paper or any other-.suitable material, the one face Aofwhich is coated or has otherwise imams tum or any other suitablematerial, orV mix ture lof materials.'

applied thereto a plastic form 2 of asphal- My improved" methodcontemplates the production of a structural elementgutilizing such abacking for a covering as above described upon which is anchored laths,slats, strips or the like, and in carrying out this' object a lath,slat, strip or the like 3 is provided, the side edges of which areconc'avely rooved for the longitudinal lengththereo These grooves mayAably in a heated stage, and while in this A v4stage a plurality oflaths, slats, strips or th like 3 are pressed into the asphaltum 4, in

a uniform, desired spaced-apart relation one to the other. In thespacing of these laths, slats, strips or the like on the backing;keyways K are formed between the lower edges of the adjacent laths,slats, strips or the like when the latter are pressed into saidasphaltum. The forcing of this asphaltum through the keyways K permitssuch asphaltum to floatupwardly and spread outwardly,'nd ing a restingsurface against the walls of the grooves 4. The settlement of theupwardly forced and spread as ha-ltum, which in the drawing isdesign-atedp as 5, forms an anchorage flbetween the laths, slats, stripsor the like, and the backing, firmly securing the former in .theirrespective positions to -the latter.

As shown in Fig.A 1, the space formed between two adjacent-laths, slats,strips orthe like is substantially elliptical in cross section, and thatspace between the upper edges of two adjacent laths, slats, strips orthe like forms a keyway 6 to the elongated cavity 7 between the g'roovedwalls 4.- When the structural element thus formed is app-lived to use,it is adapted to be covered yby plaster,

lime, cement, stucco, or other similar materials which l have designatedin the drawing by the numeral 8. When the plaster material is applied tothe structural element, sufficient of the same is forced through' thekeyways 6 into the cavities 7 to fill the latter, thus'affording aAlocking means for the body of the lapplied plaster.

In Figs. 2 and2a,-I have shown a modified form. of the inventionwherein, in addition to those novel features illustrated in Figs. l andla, l have provided the laths, slats, strips or the like in the upperfaces thereof, as shown in the drawing, with dovetail grooves `9extending the full length' thereof. rlhe -sides of this ways 10 wherebyin the application of the plaster to this form of structural element anadditional locking means is provided. The plaster, referred to as 8a inthis form, is forced -through the keyway 10 and into the dovetail groove9, binding against the oove and further locking the body of the plasterto the structural element, this locking portion of the plaster beingdesignated ink Fig. 2 as 11.

In Figs. 3 and 3, I have shown a .further .modified form illustrating anadditional anchorage for securing the laths, slats,'strips or the liketo the backing. To this end, the lower face of each lath, slat, strip orthe like is, as shown in Figs. 3 and 3, provided with a dovetail groove12 which groove provides a keyway 13 for the admission therethrough ofasphaltum, design-ated in the drawing as 14, which affords an additionalanchora e for said laths, slats, strips or the like to t e backing. Y

In Figs. 4 and 4a, which is -a still further modified form of myinvention, I have com- `bined the features of novelty illustrated in thethree previously-described forms of the invention, utilizing principallythe upper and lower dovetail constructions 9c and 12 respectively.'While I have not shown a heavier lath, slat, strip or the likeconstruction, it may be adv-anta ecus for purposes of strength andrigidity 1n this form of the invention to construct such laths, slats,strips or the like of heavier material.

In Figs. 5 and 5", a further'modiiication of the invention, I have shownthe identical construction in Figs. 1 and l, and all the featurestherein described, with the eXception that the grooves 4d as shown inythese figures are semi-cylindrical in design.

lIn Figs. 6 and 6a, I'have shown a still further modified form of theinvention identical in construction and principle as that illustrated inFigs. 2 and 2, with the exception that the grooves 4e herein shown aresemi-cylindrical in design and the locking grooves 9e of the laths,slats, strips or the like are, substantially elliptical in design.

.- Figs. 7 and 7n show a further modification of the invention identicalwith that form of the invention illustrated in Figs. 3 and 3a, involvingthe same principles thereof with the exception that the additionalanchoring grooves 12t are substantially cylindrical in design, asdistinguished from the dovetail grooves 12 of Figs. 3 and 3a, and thegrooves 4f are semi-cylindrical in design, as distinguished from theelliptical grooves 4b, of said Figs. 3 and 3a.'

Figs. 8 and 8u correspond identically in structure and principle withthe form of the invention illustrated in Figs. 4 and 4a, respectively,with the exception of the semicylindrical grooves 4g and thesubstantially elliptical grooves 9g and 12g, respectively.

In Fig. 9, I have s hown still another modified' form of my inventionwherein the laths, slats, strips or the like 3h hav-e the side'edgesthereof cut out in a V-shaped manner, providing V-.shaped grooves thefull length thereof. The keyway 'K `between the adjacent laths, slats,strips or the like afford the same means of anchorage as the keyway 6,and the same means'of locking as described in` connection with the othervarious forms of theinvention.

In Fig. 9, I have shown a slightly modified form of the inventionillustrated in Fig. 9, wherein alath, Slat, strip" or the like 3 has theupper face thereof provided with a dovetail roove 9i which affords thekeyway 10. hile I have shown this dovetail groove in the upper face ofthe lath, Slat, strip or the like to be used as a locking means for thebody ofthe plaster, it will be well understood that it may serve as ananchorage for the laths, slats, strips or the like when the latter isdisposed in the reverse position to the backing to which it is adaptedto be applied. n the other hand, it will be understood that a doubledovetail groove construction may be utilized in connection with thisform, as shown in Figs. 4 and 4a of the drawing.- p

The variations in the forms of the invention are slight but theprinciples are common to all.

I am aware of the fact that other structural elements are known, whereinlathsl with beveled sides are secured to a backing, but my improvedstructural element contemplates a vantages and accomplishments whichcannot be attainedby this former structure, and which vwill mosteiiiciently carry out the numerous objects for which it is designed.

While I have described the elements best adapted to perform thefunctions set forth, it is obvious that various changes in the form,proportion and in the minor details of construction may be resorted to,within the scope of the appended claims, without departing from thesplirit or sacrificing any of the principles of t einvention.

Having thus described my invention, I claim and desire to secure byLetters Patent 1. A construction comprising a body portion, a striphaving in each lateral side thereof a longitudinally extending groove,and a plastic adhesive material covering one side of said body portion,a portion of which enters the said grooves lto hold the strip on thebody portion.

2. A construction comprising a body portion, a strip having in'eachlateral side thereof a longitudinally extending groove, and a plasticadhesive material covering one side of said body portion, a portion ofwhich enters the said grooves to hold the strip on the body portion anda facing-material also located in said grooves and 'extending over saidstrip. V

3. In combination, a flexible sheet of ma- 5 terial having a flexibleadhesivey coating covering one side thereof, a plurality of stripsspaced apart from each other a predetermined distance and having in eachside thereof a longitdinally extending'groove; said strips beingembedded in said adhesive material, which material extends above thebottom edges of said strips and intol said grooves to rmly anchor saidstrips to said backing material.
